Objectives and Agenda (tentative)

Objectives

1. To understand the principles of total station survey.

Don't make total station survey a black box.
If one understands the principles, technical details of machine operation, data processing,
and map drawing will never be a magic.

2. To understand survey strategy for geology and geomorphology.

How to measure 3D topography, and 2D polygons, linear features, and profiles in good order, with desired resolution, in readiness for computer-aided map drawing, and without loosing accuracy.

3. To process and present the data in the most effective way.

Microsoft Excel (and/or text editor, sed, and awk) for data arrangement and adjustment. GMT for scaled plotting, DEM generation for contours, tints, and shaded relief, and EPS output for extensive uses in PC & Mac. Adobe Illustrator for details and artistic touch.
Again, no black box.


Tentative Agenda

May 8th, 2002
afternoon (Koji and volunteers)
Set up stations and backsight to put stakes and to get coordinates.

May 9th, 2002

1. Introduction (08:00 -- 08:30 lecture room)
Principles of measurement, precautions for operation.

2. Topographic survey (08:30 --11:00 somewhere in campus)
Setup [centering, backsight, coordination]
Linear features, general topography, and profiles.
Use of portable GPS to determine geographical position and orientation.

Plan for the survey

3. Wall mapping (11:00--13:30 including lunch break: outside a building)
Map a real scale trench-log mural [to be printed on 2 rows of 32" by 10 m roll paper].

Mapping an exposure with grid lines

4. Data retrieval (13:30--14:00 lecture room)
RS232C interface to PC/Mac using term application.
Distribute the data to all participants using PCMCIA card, zip, CD, or memory stick.

5. Data processing and map drawing (14:00--16:30 lecture room)

6. Conclusion (16:30--17:00 lecture room)
